llVlPROVEMENT IN FASTENERS FOR MEETING-RAILS CF SASHES.

Specification forming part of Letters Patent No. 161,652, datedApril 6,1875; application filed February 13, 1875.

CASE 0.

To all whom it may concern:

Be it known that I, STEPHEN D. ARNOLD, of New Britain, in the county ofHartford and State of Connecticut, have invented an Improvement in SashLocks, of which the following is a specification:

The object of this invention is to fasten the meeting-rails of sashestogether, and the improvement is especially available with sashes thathave a central bar or mullion.

I employ a handle that is received between the side pieces of a jaw, andto which a spring is applied, so that the handle latches upwardly into anotch when the fastening is locked.

The holder is hook-ended and operated by the handle, and with sashescontaining a central mullion, the keeper-plateis constructed so as topass upon both sides of said mullion, and thereby avoid injury to thewood-work of the sash.

In the drawing, Figure l-is a plan, partially in section of the saidsash-lock. Fig. 2 is a vertical section, and Fig. 3 is an elevation withthe sash-lock retracted; and Fig. 4 is a section of the jaw andlever-handle at the line as.

The plate a is adapted to being fastened to the top meeting-rail of thelower sash,

and above it is the box I), that is nearly semicircular in shape, andriveted to the plate a. In the curved front part of this box is anopening, through which the lever-handle 0 passes, and a notch isprovided at 2, into which the lever-handle c springs up when the sash islocked, and thereby said handle is retained until it is pressed downprevious to being turned back.

The lever-handle c is received between the side pieces of the jaw d, andattached by apin, 3, so that the lever and jaw may turn together; butthe lever may be moved slightly up or down in latching or unlatching atthe notch 2, the spring 4 serving to raise the lever.

The hook-ended holder h swings with the jaw (I, and engages with thekeeper-plate l by passing into an opening through its vertical face;said hook-ended holder being of a tapering or cam shape, so as to drawthe parts of the sashes together.

Where the lever c and jaw 61 areused in a sash wit-houta center bar ormullion, the hookended holder h will be cast in one with the jaw 61, andproject at the opposite side of the fulcrum t to said jaw; but with afastening adapted to a sash with a center bar or mullion, it isnecessary that the hook-ended holder be placed sufliciently at one sideof the fastening to pass into the keeper-plate l clear of the saidmullion, so as to avoid cutting such mullion. I therefore employ thelink a, that is hinged at its ends to the lugs that project from thesides of the hook and jaw, respectively, as shown in Fig.1, and thekeeper-plate l is made of a box shape, with the top and back portionsnotched, as at Z, so as to set in front and at the sides of the centerbar or mullion of the upper sash, but only project in front of themullion the thickness of the front or keeper plate of the box. Behindthis front keeper-plate the hook-ended holder catches when the lock ismoved to secure the sashes.

The box of the fastening is provided with a knob, r, beneath which is aconical skirt, 8, that is separate from the knob, but is held in placeby the screw it of the knob, that passes into the top plate of the box.

By this construction the ornamental knob can be applied to or removedfrom the sashlock, the other parts being independent thereof, so thattwo styles of sash-locks can be made from the same patterns.

I claim as my invention- 1. The lever-handle 0, jolnted to the jaw d,and provided with a spring, in combination with the hook-ended holder h,plate a, box Z), and curved front plate, notched at 2, as and for thepurposes set forth.

2. The lever-handle c, jointed to the jaw 61, in combination with thehook-ended holder h, link a, and keeper-plate l, substantially as setforth.

3. The sash-lock, made with alever and hookended holder between theplate a and box b, in combination with the knob 1" and skirt 8',connected by a screw to the top of the box I), as set forth.

Signed by methis 9th day of February, 1875.

S. D. ARNOLD.
